What brings the gang back together? If you've been watching this season of "'Til Death," you're aware that Tim Sharpp's character, Doug, has been convinced that he is trapped in a sitcom. To treat his insanity, Doug has been seeing Dr. Bialik, a fictionalized version of Mayim Bialik played by Bialik herself and inspired by her real life PhD in Neuroscience.

The April 25th episode is centered on Dr. Bialik's hopes to cure Doug by bringing him in for a group therapy session with all of her old "Blossom" castmates -- who will be playing themselves.
